Ruby script to make a release from SVN trunk.

Assumes a repository structure of:

/path/to/Trunk
/path/to/Releases/YYYY-MM-DD--XX

Should be easy enough to modify to suit your needs. Comments welcome :)

Example usage:

vi /usr/local/bin/release (and dump snippet into it)
chmod +x /usr/local/bin/release
cd /path/to/checked-out-trunk
release

#!/usr/bin/ruby

today = Time.now.strftime('%Y-%m-%d')

if `svn info`.to_a[1] !~ /^URL: (.*)\/Trunk$/
        puts "Repository invalid. Must be in Trunk."
        exit
end

repo_url = $1

repo = repo_url.split('/').last

release_url = repo_url + "/Releases"

if `svn ls #{release_url}`.to_a.last =~ /#{today}--(\d+)/
        num = $1.to_i + 1
else
        num = 1
end

release = "#{today}--#{num}"

cmd = "svn copy #{repo_url}/Trunk #{release_url}/#{release} -m 'copy #{repo} trunk to release #{release}'"
puts cmd
puts

print "Execute command? "

if gets.chomp.upcase != 'Y'
        puts "Nothing done."
        exit
end

`#{cmd}`
puts "Copied as #{release}."
puts "Execute on the remote machine:"
puts "svn switch #{release_url}/#{release}"
